Furthermore, cervical dilation happens with normal positioning and posture of a fetus presented during delivery but lack of uterine contraction due to various reasons leads to dystocia problems.
59.16% and 40.84% rate of dystocia incidence in Murrah buffalo because of maternal causes was in agreement with current results () Disagree with our recorded data of cases showing hypocalcemia and exhibited signs of milk fever at the beginning of calving, which related to 5.9% of uterine inertia incidence rate.
In addition to that, age, season of calving, calf gender, nutrition, hormonal status of cow-buffalo at pre parturient time also being consider as factors affecting on dystocia as well as the genetic factors ().
The fetal monstrosity’s rates are higher degree than hereditary deformities that been recorded in river buffalo and this rate still within minor rate due to lack in registered cases in veterinary clinics ().
tocia were Primary Uterine inertia (22.85) but incomplete dilation of cervix (20%), uterine torsion (14.28) and Narrow pelvis in buffaloes (5.72%).
While the main fetal cause was mal disposition of the fetus in Iraqi cow buffaloes (17.15%),because of lateral deviation of the head, downward displacement of the head, bilateral carpal flexion, bilateral shoulder flexion, bilateral hock flexion.Results All the cow buffaloes were accessible to the Veterinary Clinical 12 to 24 hours after the onset of fetal expulsion (second stage of labor).The incidence of different causes of dystocia is presented in (A) Dead male buffaloes fetal Ascites after delivery by penetrated of abdominal wall and then lubrication and forced extraction the Fetus.7.4% of neonate anomalies were classified as fetal causes of dystocia cases in Brazilian cow-buffalo, especially in the Murrah buffalo’s breeds and classify as congenital anomalies (arthrogryposis, myotonic, and mechano-bullous genodermatoses) ().Insufficient cervical dilation is rare in cow-buffalo as a cause of maternal dystocia due to the delivery position of an animal and it’s less than 5.1% of total cervical dystocia reasons in buffalo compare to high rate of ring womb in cattle ().Pleuriparous cow’s buffalo defined as the greater incidence rate of uterine torsion with major ratio of dystocia during second and third calving with right sided torsion ().Left side uterine torsion might be happen when the rumen was partially filled and the degree of torsion in most cases a round 90° -180° which almost lead to rapid fetal death and uterine adhesions with visceral organs could be developed, uterine torsion must be considered emergency cases in such cases ().In this study, dystocia weather maternal and / or fetal causes in Iraqi cow-buffaloes were analyzed.A total of 35 cow-buffaloes were admitted to the Clinic College of Veterinary Medicine, Mosul University 12 to 24 hours after starting delivery. Either maternal or fetal (37.1%) in origin (62.85%), The maternal one showed a prevalence of 22.85%, 20%, 14.28%, 5.72% due to primary uterine inertia, incomplete dilation of a cervix, uterine torsion and narrow pelvis in buffaloes respectively.
